Measures and measurement techniques in the Federal Law On Ensuring the Uniformity of Measures

The following article covers the issues of practical application of the Federal Law of 2008 On Ensuring the Uniformity of Measures. The Federal Law differs from its 1993 edition as it has a number of new provisions. In order to reduce the level of government regulations the Federal Law uses measurements that have set mandatory requirements. Measurements are being monitored by the Federal state metrological supervision. New provisions introduced some complexities in determining the range of measuring means that have to be verified. The conclusion of the article contains suggestions on how to solve the problem.

Keywords: measurement, measuring instrument, measurement result, error of a measuring instrument, measurement accuracy, accuracy class, uniformity of measurement.

Application of the P-theorem for analysis of the relationship obtained for Coriolis flowmeters

Method of Coriolis for measuring flow rate and quantity of gases and liquids are some of the promising methods that implement the playback unit mass flow. Therefore ways to increase their accuracy and reliability play an important role for science and technology. As part of this work presents the results of the use of P-theorem to analyze the relationships between flow transducer design parameters, as well as the derivation of relations that establish the relationship between these parameters and indicators that measure the flow. The paper also analyzed the material flow measurement uncertainties.

Keywords: Coriolis flowmeter, P-theorem, accuracy, quantity, flow rate.

Monitoring, cataloguing and management of measuring equipment for scientific issledovaniy

The analysis of the programs of modernization and innovative development of technological economy, which showed that their target efficiency and economic are largely determined by the condition of the park of measuring equipment and the validity of the selection of modern measuring technology. It is shown that for this problem, the developed information-analytical system of cataloging products for scientific research. The main characteristics and capabilities of this system. It is shown that with the help of information-analytical system of management, (network-centric system), can use the global computer network for communication of developers and users with a database of information about the exploited, manufactured and developed tools to measure, control and measuring devices, testing and diagnostic equipment. It is expected that the use of such a system of management in the selection, development, examination of instruments for scientific studies will undoubtedly contribute to the improvement of economic efficiency and target effectiveness of technological economy.

Keywords: instruments, information-analytical systems, network-centric management, the metrological and normative guarantee.

New requirements for verification of liquids flowmeters

Normative documents that define requirements for the verification of measuring instruments before and after 2015 Regulations for Metrology PR 50.2.006-94 and Order 1815 of Industry and Trade Ministry on July 2, 2015 differ significantly in terms of the definition of measuring ranges, which should be carried out verification. Stricter requirements for verification leads to the need to increase the maximum reproducible consumptions of calibration rigs used in the verification of flow meters and liquid counters as the volume flow gauges. Available in most regions of Russia calibration rigs for the most part do not provide the requirements of the Order 1815, therefore important task of instrumentation industry has development and production of large-capacity calibration rigs.

Keywords: metrology, verification, flow meter, liquid counter, measurement.
